WATCH ABOVE: The public discourse over a southwest transitway reached a boiling point and in response the mayor is halting all future meetings. At several public engagement open houses concerned residents packed the meetings and city employees say they became the targets of bullying, intimidation and abuse. Jill Croteau reports.

“There was yelling, there was swearing, there was pushing and shoving,” Nenshi said of the Woodcreek Community Association meeting.

“There were incidents of physical assault on City of Calgary staff. There were threats of violence, and yes, there was a death threat.”

Nenshi called it “unCalgarian” and referred to an October meeting at which a city employee was assaulted by a community member, “including ripping at her clothing, pulling off her name tag, and yelling insulting comments at her.”

WATCH: Calgary Mayor Nenshi says his staff was threatened at a meeting on the Southwest Transitway project.

“I will not tolerate threats, violence, or intimidation against other citizens or against my colleagues at the City of Calgary,” he said. “Public engagement needs to be a safe space for citizens—a place where anyone can feel free to ask questions without being intimidated and it must be a safe workplace for dedicated public servants. I am deeply disappointed with what happened last night.”

Ready to Engage! member Rick Donkers said his group wasn’t doing anything wrong, and shouldn’t be portrayed that way by the mayor.

“This wasn’t about Ready to Engage doing anything … this is about the city trying to intimidate citizens who are merely doing their democratic right to ask questions,” he said. “It’s the citizens of Calgary who are asking these questions, and now we’re being portrayed as thugs? It’s reprehensible.”

The transitway project on 14 Street S.W. is already approved and funded, and construction could start this year. The meetings were meant to fine tune its design.

Nenshi said public engagement will continue, but only through online feedback systems and virtual town halls.
